Salt & Pepper Shakers too.

From CW;
Antique shakers was a type of slip-decorated ceramic called mochaware. Effects included dark treelike shapes that were produced by dropping an acidic solution containing urine (how, one wonders, did they discover that…) onto an object’s wet surface before firing. Other designs such as cat’s eyes were achieved by applying multiple colors of slip from a multi-chambered pot in repeated or hand-manipulated patterns. As for the shapes of the shakers themselves, they were typically rounded at the top and footed at the base with pear-shaped bodies, although some were produced as straight-sided cylinders.
